GAR-SEAL LOCK.

To all whom it may concern:

Be it known that I, EMIL TYDEN, a citizen of the United States, residing at Hastings, in the county of Barry and State of Michigan, have invented new and useful Improvements in Car-Seal Locks, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide an improved seal lock for railway cars, designed to be sealed in such manner that after the car is unlocked and opened it cannot be completely re-sealed until the car has been moved on the track or disturbed to an extent equivalent to such movement, thus preventing the unauthorized entry of the car and re-sealing 1t with an imitation seal while the car remains entirely at rest on the track.

It consists in the elements and features of construction shown and described, as indicated in the claims.

In the drawings :Figure 1 is a front elevation of a portion of a car body and door having a lock embodying the present inven tion, showing the same fully sealed. Fig. 2 is an elevation of the lock mechanism with the front cap of the lock removed. Fig. 3 is a horizontal section at the line, 33, on Fig. 2, with the cap in position. Fig. 4: is a section at the line, 44, on Fig. 3. Fig. 5 is a detail front elevation showing the lock partly sealed, having the main locking bolt sealed with a certain form of seal. Fig. 6 is a detail front elevation with a portion of the case broken away to disclose part of the interior structure, with the parts in the condition and positions which would be occupied if the car had been unlocked and resealed as far as possible without moving the car. Fig. 7 is a view similar to Fig. 2 showing a modified device embodying a portion of this invention. Fig. 7? is a section at the line, on Fig. 7. Fig. 8 is a plan view of a suitable form of seal.

In the drawings, the look case, 1, is shown secured upon a car body, 2, in the usual position for securing a sliding door by means of a hasp, 3, on the door, engaging the staple, 4, of the lock, and there secured by the main bolt, 5, of the lock, said main bolt being mounted for vertical sliding in the casing, 1. The main bolt is shown provided with a seal-receiving aperture, 5*, through which any form of flat seal may Specification of Letters Patent.

be inserted and secured in any known manner. In the drawings a particular form of seal is shown which will be hereinafter described, being adapted to certain preferred modes of use of the lock herein shown. The seal aperture, 5 is in the end portion of the bolt below' the staple, 4:. In the casing, 1, there is mounted for sliding parallel with the main bolt, 5, an auxiliary bolt or tumbler, 7, which has also a seal-receiving aperture, 7 in the lower end portion of said auxiliary bolt, said lower end portion being adapted to protrude fro-m the casing at fully locked and sealed position so as to expose said seal aperture, 7 for the insertion of a seal therethrough; and this auxiliary bolt may be made to operate for locking, as illus trated, by extending the hasp, 3, over an auxiliary staple, 4*, for engagement of the hasp and the auxiliary bolt. The main bolt, 5, has an arm, 5, extending off from said main bolt across the auxiliary bolt, 7, and between shoulders, 7 and 7 on said auxiliary bolt which are so located that at the unlocked position of the main bolt, 5, said arm, 5, holds the auxiliary bolt, 7, out of seal-receiving position. The distance between the shoulders, 7 and 7 is such that the main bolt, 5, may be returned to look ing position without restoring the position of the auxiliary bolt, 7, said arm, 5, merely moving between the shoulders, 7 and 7 in its locking movement. \Vithin the casing, there is pivotally supportedfor swinging back and forth lengthwise of the car,that is, parallel to the plane of the back plate of the casing,a pendulous member, 8. This member may be pivoted upon the auxiliary bolt, 7, but this is not essential though the further details of construction shown are adapted to this mode of pivoting said pendulous member.

A catch device is provided in the casing for automatically engaging the auxiliary bolt, 7, with the casing at its withdrawn position,that is, at the position at which the seal aperture, 7, is within the casing and inaccessible for sealing. As a matter of convenience, this catch device may be pivoted upon the auxiliary bolt, 7 and engage an abutment on the casing, as shown in the drawings, said catch device being a hook, 9, having acatch nose, 9 with an oblique face, which, in the upward or withdrawing movement of the auxiliary bolt, encounters a fixed stud, 10, on the casing,

and being deflected past it falls back into engagement with it at the most withdrawn position of the auxiliary bolt. As illustrated, this engaging action of the catch hook is effected by gravity caused by the fact that the catch hook has an arm, 9 extending off from its pivoted end and overhanging an arm, 8, which extends off from the pivoted end of the pendulous member, 8, and which is stopped by said arm, 8*, at a position at which the oblique face of the nose, 9 will encounter the stud, 10, in the withdrawing movement of the auxiliary bolt, and whose weight tends to swing the catch hook back over said stud after it has been deflected to pass it. The reason for making the catch hook a separate piece from the member, 8, is that said member, 8, by this means acquires some impetus in its swing before the frictional resistance to disengagement of the hook from the stud is encountered.

In using this lock, it is designed that the shipper having loaded the car will close the door and lock it by dropping the main bolt, 5, into locked position and will then secure that main bolt by a seal of any suitable form, as, for example, the seal, 12, inserted through the seal aperture, 5, and secured by bending it at the line, 12, to prevent its withdrawal, (the seal being of such character that it cannot be straightened back into position for withdrawal without breaking at the line, 12*). When the car which is presumed to have been loaded on the shippers track is picked up by the train, the first movement which it receives in coupling to the train or moving it from the loading track, will cause the pendulous member, 8, to swing, and by means of the arm, 8", encountering the arm, 9 of the catch hook to disengage the catch hook from the stud, 10, whereupon the auxiliary bolt, 7, will drop and expose the seal aperture, 7, outside the casing. The train conductor, or other representative of the carrier, will now apply a seal to said auxiliary bolt, 7, inserting it through the seal aperture, 7*. For this purpose, the seal, 12, is shown double, having an easy breaking line at 12 so that the conductor may detach the member at the left of said breaking line, and use it as a second seal to secure the auxiliary bolt, 7, inserting its reduced end portion through the seal aperture, 7*, and bending it at the weakened line, 12. The use of the double seal-shown is not essential. Any seal may be used by the shipper, and any other seal may be used bv the carrier. The duplex seal shown has, however, certain advantages, as will hereinafter appear. If at any point during transportation, when the car is standing still on the track, an unauthorized person breaks the seals and unlocks the car, the unlocking movement of the may move the bolt, 5, to locking positi0n, and may apply an imitation or duplicate 1 seal to said locking bolt, and to that extent restore the original appearance, for the pur- .pose of preventing detection of the unauthorized intrusion; but he cannot re-seal the auxiliary bolt, because its seal aperture is at an inaccessible position in the casing and will so remain until some movement of the car causes the pendulous member, 8, to

release the catch hook and to permit the auxiliary bolt to protrude to seal-receiving fiend. A thief, taking opportunity of the halting of the car in transit to break in and of the fact that the car had been tampered gwith; and the provision of this auxiliary 5 bolt automatically withheld from sealing position until the car is moved, thus practically iinsures a prompt detection of felonious intrusion into a car thus sealed.

In order that the pendulous member, 8,

I may not be kept constantly swinging on its pivot while the car is traveling, which would 5 tend to cause unnecessary wear at the pivot, it is formed with rib, 8, having a tapered lower terminal, 8 which in the descending movement of the auxiliary bolt enters a tapered notch, 5 in the arm, 5, which holds the pendulous member fixed against swinging at all times when the auxiliary bolt is at seal-receiving position, or the main bolt, f 5, is at unlocked position. From this it re sults that the pendulous member can swing but once for each instance of unlocking the car; for it is only when the car has been unlocked by lifting the main bolt, 5, and then has been locked by dropping that bolt, leaving the auxiliary bolt hooked up at withdrawn position, that the pendulous member can swing; and as soon as it swings once, the j auxiliary bolt is released and drops into the position at which the pendulous member is flocked against swinging, where it will remain until the car is again unlocked and re-locked.

The duplex or double seal shown in the drawings is especially adapted for use with the lock of the character shown, by reason of the advantages afforded by certain features of that seal which will now be pointed out. It is designed that these seals shall 7 be furnished'in bunches on a retaining ring for which an aperture, 12*, is made in the stub member, 12*, of the seal. The seals are identified by a serial number marked upon the stub and also upon the left-hand member of the seal which is applied by the representative of the carrier as hereinafter explained. It is designed that the shipper shall break off the seal from the stub at the perforated line provided to facilitate such breaking and insert the right hand reduced end of the right-hand member through the seal, bending the protruding portion at a line crossing the aperture, 1%, to fold the end portion back against the bolt. This end portion may be provided with characters to denote either the shipper or the carrier, as preferred. The left-hand member of the seal has the serial number corresponding with the number on the stub retained by the shipper, but said number on said lefthand member is placed upon the rear or inner surface of the seal-so as to be not legibly accessible after the seal with the two members not yet broken apart has been applied by the shipper, as above described. The train conductor being obliged to record the seal number must fold back the left-hand member of the seal in order to read the number, and the seal is so weakened at the breaking line, 12 that it will break upon being thus folded back, and this construction tends to prevent the conductor from omitting to use the left-hand member of the seal for sealing the auxiliary bolt, 7. It will be observed that the number remains on the lefthand member of the seal when it is applied in sealing said auxiliary bolt, and serves as identification of the seal in subsequent inspections.

It will be understood that the seal illustrated is adapted to perform the function of a seal by virtue of the fact that being weakened at the line for which it is folded for retaining it in the bolt, it will break at this line upon being straightened back, as will be necessary in order to withdraw it from the bolt, so that any attempt to remove the seal will destroy it as a seal,that is, will prevent it from being re-applied so as to appear as if it had not been disturbed.

I have termed the part, 7, a bolt because it has a bolt-like movement, and by its protrusion from the casing is adapted to be utilized directly in looking if desired; but by virtue of its function, as described, in connection with the main bolt, it may properly be considered as a tumbler or bolt-securing member; and I do not wish to be understood by the use of the term bolt applied to this part, 7, as limiting myself to a device having independent locking ca pacity; for it will be evident upon consideration of the structure shown and the mode of operation described that an important part of the result obtained is entirely independent of the fact that the auxiliary bolt actually efiects looking, it being sufiicient that it is adapted to receive a seal and cannot be withdrawn into the case until the seal .is removed. On the other hand, it will be observed that when the auxiliary bolt is an actual locking bolt, there is no necessity for a connection from the main bolt to the auxiliary bolt by which the latter is withdrawn when the former is moved to unlocked position, though such connection may still be retained without disadvantage, but in its absence, or if it. should be broken off, the person opening the car will disengage both bolts by hand, withdrawing the main bolt in the usual manner, and push ing up the auxiliary bolt with one finger until it becomes engaged with the catch which will retain it out of locking position. It will be observed also that an important part of the purpose of the device is independent-of the main bolt, when the auxiliary bolt, is an actual locking bolt; because when the car is loaded by the employees of the carrier and is immediately ready for sealing by the carrier, or when, for any other reason there is no interval between the loading and the time when the car is moved, during which the protection of scaling is required, only the carriers seal may be applied, and that to the auxiliary I bolt. And in such case, if the car is afterward entered, the seal being broken for that purpose, it cannot be re-sealed until the car has been moved on the track, and thus a principal purpose of the device will be effected without bringing the main bolt into operation, or even without the presence of more than the one bolt, and that one corresponding to the bolt termed the auxil iary bolt in the construction illustrated.

In Fig. 7 there is illustrated a modification which comprises one of the main features of the invention as embodied in the preceding figures, namely, the provision of a seal-receiving member which, after once unlocking, cannot be returned to seal-receiving position until the car has been moved or disturbed on the track. In this form the main locking bolt operates substantially as in the form previously described, but the auxiliary device for receiving the second seal is a lever pivoted in the casing having an up-standing arm, 20, weighted at its upper end, and which has a downwardly-extending projection, 22, for thrusting out of the case to receive the seal. hen this sealreceiving end, 22, is withdrawn within the casing the center of gravity of the lever is carried sufficiently past the pivot axis to counter-balance the projection, 22, and cause the device to be held normally by gravity at that position,that is, with the seal-receiving terminal withdrawn into the case. When the main locking bolt is lifted in the unlocking movement, it encounters the lever, 20, at any suitable point for rocking the up-standing arm, 20,'past the fulcrum in the direction for withdrawing the seal-receiving end, 22, into the case where it is held with the seal aperture inaccessible until some movement of the car on the track causes the weighted upper end of the tip-standing arm, 20, to receive an impetus which carries it back past the fulcrum, whereupon, being over-balanced at the side toward whichit thus moves, the movement will be continued and the seal-receiving terminal, 22, will be thrust out into accessible position outside of the case so that a seal may be applied to it; but if the car has been unauthorizedly opened, or if the main locking bolt has been unauthorizedly withdrawn from unlocking position, the seal in the protruding end, 22, being broken and removed for that purpose, the lock cannot be re-sealed until the car has been afterward moved on the track. In this form it is convenient to effect the engagement of the auxiliary seal-receiving device by the main locking bolt in the unlock ing movement by having the arm of the main locking bolt which actuates the said auxiliary member make it encounter with said member against the tip-standing arm, 20, by means of a forwardly-projecting finger, 5
